Abstract

A structure of UPS comprises a case having an opening over which is mounted a cover. A fastening slot is provided on an inner side of the case proximate to the opening. Two outer lateral sides of the case further include a plurality of heat dissipating elements. The cover further includes at least a fastening projection corresponding to the fastening slot. The cover thereby detachably assembles with the case to enable a change of internal components of the UPS. The structure of the UPS further comprises an annular voltage transformer having a reduced size, the general size of the UPS is thereby reduced to allow convenient carrying and easy mounting in a reduced mounting space.

Description

[0001] The invention relates to an uninterrupted power supply and, more particularly, to an uninterrupted power supply that is dimensionally reduced so as to enable a convenient mounting. BACKGROUND OF THE INVENTION

[0002] Uninterrupted power supply (UPS) devices of approximately 1000 watts or less electrical power are principally used in computers, computer peripheral components, or other conventional machines. In the case of computers, because some data stored in the memory when the computer is turned on may be subsequently erased if the power is turned off, the UPS device allows to provide the necessary power supply when the external local power is turned off. The UPS is therefore an important device that enables to prevent accidental data erasure due to power supply cutoff.

[0003] The general structure of a traditional UPS device principally comprises a connecting circuitry, an iron-core voltage transformer electrically connected to the connecting circuitry, and a charging battery...

Embodiment Construction

[0012] Wherever possible in the following description, like reference numerals will refer to like elements and parts unless otherwise illustrated.

[0013] FIG. 1 and FIG. 2 are respectively a general perspective view and an assembly of an uninterrupted power supply according to an embodiment of the invention. As illustrated, a structure of uninterrupted power supply (UPS) of the invention comprises a case 10 in which is mounted an annular voltage transformer 36, a cover 20 mounted to the case 10, and heat dissipating elements 11 disposed in radiating manner correspondingly on two lateral sides of the case 10. Via a detachable mount of the cover 20 on the case 10, the user can conveniently change the internal components of the UPS. Furthermore, by using an annular voltage transformer 36 that has a dimensionally reduced size, the general size of the UPS is reduced to allow a convenient carrying and a reduced space occupation. Via the heat dissipating elements 311, the heat irradiated fr...
